I bought a brand new windscreen for the equipe and that was £120 fitted so i would guess around £60 brand new if someone supplied it to you, contact the small independant screen fitters their prices are realistic
I paid £120 from a local guy called totton windscreens, when i tried autoglass and the other insrance rip offs they quoted £400 and over

THATS THE REAL REASON OUR INSURANCE IS SO HIGH - rip off repairers with over inflated prices with guaranteed work from insurance companies

well from a small local company, he wanted 120 to remove only. front and rear screens.
Maybe its worth shopping around with other small companys before i decide.
I dont know if you can still buy the front and rear screen seals for these anymore or whether they use a retro fit product.
